Breaking On Value Change

You can set an On Value Change breakpoint to stop program execution when the contents of a variable change.
To set an On Value Change breakpoint:
- 1. In the Debugging Window, choose Windows
Breakpoints. Or, choose Execute
Set Breakpoints.
- 2. If the Details pane of the Breakpoints window is not displayed, click the Add/Change Breakpoint button (the Add/Change Breakpoint button toggles to Hide Details).
- 3. Choose Event
On Value Change and type the variable you want to view in the Event text box. For example:
var, or var[10]
- 4. Choose Action
Stop.
- 5. Click Add.
- The breakpoint triggers after the line where the variable's value changed.
Note - To improve execution speed, limit single-stepping to a particular function using Option
While in.
